Add them up and divide the sum by 2.
Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product. If all of the numbers being multiplied together are odd, the product will be odd. If one or more of the numbers is even, the product will be even.
If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.
You can't. Only whole numbers are odd or even.
Type your answer here... Dertermine three consecutive even numbers who's sum is 42?
Yes, all you have to do is to count the number of ODD numbers in the list. If it is odd, then the sum will be odd; if even, so will the sum. Knowing this can help you run a quick validity check when you sum up a list of numbers. (The method works because: a) the sum of two even numbers is even, and b) the sum pf two odd numbers is even, but c) the sum of an even number and an odd number is odd. Hence, if you only determine whether there are any unpaired odd numbers, you know the answer.)
if there is an od quantity of odd numbers the sum will be odd....example 1 3 4 6 has two odds so it will be even =14 1 3 5 6 has three odds and it is = 15
It doesn't matter what the first number is. All that matters is the ones place to determine if the number is odd or even.
Just add the end numbers, so 3 + 5 + 4 + 7 = 19 which is odd. Alternatively, ignore even numbers [such as 4], and two odd numbers [3 and 5] added always make an even number , which leaves and odd number  so the answer will be odd. Example; five hundred different numbers, where 483 are even and 17 are odd, then no matter what the actual 500 numbers are the answer will be odd, as there is an odd  quantity of odd numbers.
The parity rules are: Odd + Odd = Even Even + Even = Even Odd + Even = Odd Even + Odd = Odd So the parity where one number is even is that of the other number. This means that you can go through a list of numbers and ignore all the even numbers. Every PAIR of odd numbers has even parity and by the previous paragraph, even parity can be ignored. So you can pair off odd numbers and ignore them.
Those are called "even numbers".Those are called "even numbers".Those are called "even numbers".Those are called "even numbers".
If you multiply one even number by one odd number, the result is always even. In general, if you multiply several numbers, and at least one of the numbers is even, the product is always even. This is because "even" means "multiple of 2", and if one of the factors contains a 2 as a factor, so will the product.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
Count how many of the numbers are odd. If an odd number of them are odd, then their sum is odd. If an even number of them are odd, then their sum is even.
All even numbers are composite except 2 itself which is a prime number because it has only two factors which are itself and one.
it is the integers of even numbers which divide all the even numbers
even numbers:the numbers which are divisible by 2 are called even numbers.2,4,6,8,10.....odd numbers:the numbers that are not divisible by 2 are even numbers. for example 1,3,5,7,9,....
Not all composite numbers are even, but all even numbers except 2 are composite.
It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.
At least one of the two numbers has to be even, but both can be even.
No even numbers add up to 9. The sum of even numbers is always an even number.
The answer will be even because if the numbers are even, the answer will be even.
2,4,6,8,10,12,14,16,18,20,22,24,26,28,30.......... And so on. Even numbers are the other numbers like: 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31......... And so on.
All numbers divisible by 2 are even numbers.
Even plus even equals even. Odd plus odd equals odd. Odd plus even equals odd. 13 + 45 (odd plus odd) will be even. Even plus 24 will be even. Even plus 17will be odd. 13 + 45 + 24 + 17 will be odd.
